Getting rid of ' ' and sidebar options

The easiest way is to hide it by using the admin screen Appearance – Editor to edit the theme’s style.css file. Add this at the end:

[class*="foundicon-"] {display: none !important;}

I’m guessing a little, because I haven’t tried this myself with this particular theme.

You have to be logged in as an administrator to have the right level of access. If you install an update to the theme, you’ll have to make the change again. To avoid this drawback you can write a child theme, which is pretty easy. Another way is to install a plugin that lets you add CSS style rules.

You’re a star! Thank you so much x

That selector will hide everything else that makes use of that class in its part too.

The ideal is to not output the secondary sidebar at all, but this depends on how your theme codes the sidebar template. To display none it using CSS, it’s better to use a more direct selector.

Like this

#secondary { display: none; }

or this

.sidebar-button { display: none; }

The theme you are using offers its own support forum. Might as well use that to let the theme author know and provide direct support or an update. There is a way to code the sidebar template so that it won’t output the markup when there is no widget in it.
